There’s nothing illogical about it. Police uses body cameras because they do want to use them. Can you think of any law that was passed against police? There were huge protests demanding police reform and nothing happened. The only thing that activists “won” were the body cams. That’s because police and prosecutors find them useful. Sure, police was skeptical at first because the cameras were marketed as tool for accountability but as soon as they realized that they are actually tool for surveillance the adoption moved fast. That’s the whole point the articles I’ve linked make and you find so hard to understand.

The DEA will stop using them because Trump’s administration is incompetent and makes a lot of stupid decisions. Other agencies could stop using them but for now decided against it.
